GAS-BURNER.

SPECIFICATION forming part of Letters Patent 1 l'o. 353 187, datedNovember 23, 1886.

Application filed December 17, 1885. Serial No. 155,975. (No modeLl Toall whom it may concern.-

Be it known that I, JAMES S. \VETHERED,

a citizen of the United States, residing at San Francisco, in the countyof San Francisco and State of California, have invented new and usefulImprovements in Gas-Burners, of which the following is a specification.

My invention relates to an improved gasburner, comprising an outer shellor gas passage, an inner shell or air-passage having airinlets extendingthrough the gas-passage, said shells being converged at the top to forma burner tip or tips, an auxiliary gas jet or nipple at the base of theinner shell, and an incombustible heat accumulating material orstructure inclosed in the inner shell above said auxiliary gas-jet.

The invention also consists in the construction and combination of partsin a gas-burner, as will be hereinafter more fully set forth.

In the annexed drawings, illustrating my invention, Figure 1 is avertical section of my improved gas burner. Fig. 2 isa bottom view ofthe same. Figs. 3and 4 represent a burnertip.

In order to enable those skilled in the art to make and use my improvedgas-burner, I will now proceed to describe its construction withreference to the accompanying drawings.

In the drawings, the numeral 1 designates the outer shell or casing ofthe burner, which may be of any suitable or preferred form, and

is made of metal or other appropriate material. At the lower end of theburner-casing 1 is an internally-threaded tubular neck, 2, by which theburner is attached to the nozzle 3 of a gas-supply pipe, as shown inFig. 1. The burner-shell may be made in one piece, or in two or moreparts connected by flanges 4, or otherwise, as may be preferred.

Within the outer shell or casing, 1, is inclosed an inner and smallershell, 5, the form of which corresponds with that of the outer shell. Atthe bot-tom or in the lower part of both shells 4 5 are perforations 6,connected by tubes 7 ,through which air is admitted to the interior ofthe inner shell. Inthe lower part of the inner shell, 5, andcommunicating with the tubular neck 2 of the outer shell, is a-smallgas-jet, 8, by

which the air supplied tothe burner is heated 53 before being passed tothe burnertip.

The shells l and 5 are so made as to converge at the top to form aburner-tip, 9, and the space 10 between the shells communicates withthis tip at one end and with the gas in 5 lot or neck 2 at the otherend.

I employ a quantity of loosely-packed as- .bestus, 11, supported upon aperforated diaphragm or wire-gauze partition, 12, arranged to preventthe asbestus fibers from falling onto the gasjet 8. It will be seen thatair entering theinlets 7 will pass through the perforated diaphragm 12and into and through the mass of heated asbestus. The feed of the air isthus sufficiently retarded to allow ample opportunity for greatlyincreasing its temperature before it is permitted to reach theburner-tip. By means of the gasjet S the burner and its contents aremaintained at a high temperature throughout. It is therefore evident 7cthat the gassupply which passes through the space 10 between theburner-shells will also be raised to a high temperature before reachingthe burner-tip, where it comes in contact with the heated air. Vvithasuflicient supply of gas an intense combustion can be maintained at theburner-tip, and by the thorough intermixture of heated gas and air thecombustible gaseous constituents will be thoroughly consumed.

The burner-tip may be annular to produce a hollow flame, having acentral air supply; or, if desired, the tip may have two or more slits,13, for exit of gas, with an air-opening, 14:, located between. er maybe provided with a deflecting plate, button, or disk, 15, to direct theair-supply against the inner side of the flame and insure a thoroughmixture of air and gas. The gas jet Sis provided with a cock, l6, and,if de- .90 sired, the burner proper, or the pipe or tube to which it isattached, may be furnished with any suitable or well-known regulatingdevice.

When the burner is to be used, the gas is turned on and ignited at thejet or nipple 8', 95 thereby rapidly heating the burner and itscontents. The gas and air passed through the burner thus have theirtemperatures raised In either case the burnrapidly, and when brought incontact and ignited at the bu rner-tip will combinewith great energy.

A burner of this construction can be used toadvantage either for heatingor illuminating purposes.

A burner of this construction can be readily attached to a chandelier orother support for illuminating purposes, and it is also adapted for usein heating.

What I claim as my invention is 1. In a gas-burner, the combination ofan outer shell or gas-passage, an inner shell or air-passage, air-inletsextended through the gas -passage, an incombustible material inclosed inthe inner shell and extending entirely across the space Within the sameand forming circuitous air-passages, a foraminous plate sustaining saidmaterial, and an auxiliary gas-jet located beneath said foraininousplate, substantially as specified.

2. In a gas-burner, the combination of an outer shell or gas-passage, aninner shell or air-passage, a gas jet or nipple located in the lowerpart of the inner shell, a perforated transverse diaphragm above saidinternal gasjet, and an asbestus filling inclosed in the inner shell andresting on said peforated diaphragm, substantially as described.

In testimony whereof Iaffix my signature in presence of two Witnesses.
